An athlete is running along a flat training track.
The mass of the athlete is 72 kg.
Calculate the kinetic energy of the athlete when they are running at a speed of 5.0 m/s.
Use the equation:
kinetic energy=0.5×mass×speed2 \text{kinetic energy} = 0.5 \times \text{mass} \times \text{speed}^2 kinetic energy=0.5×mass×speed2
